To all whom it may concem;

Be it. known that I, Jacon ,Boc-nm, a citizen of the" Swiss Republic, residing at Laendliweg 18, Baden, Switzerland; have invented certain new and useful Improve! rnen'ts in and Relating to the Driving Mechanism' of Vehicles, or which the followingiis a s Jecification.

his invention relatesto the driving of -vehicles more particularly in which motors are placed at,some distance above the driving wheels and has for its object to provide a driving system' lighter in weight and cheaper to construct than thahsual systems.

The invention consistsin a driving system for electrically driven vehicles with motors above the "wheelsin which two'motors act through the intermediary of suitably jointed coupling rods'on. a common point of the horizontal coupling rods connecting the drivingcranks.

- 'pling rods s Referring to theaccompanying diagrammatic drawings Figure 1 shows an example according 'to the PIGSBIIt'lIIVGDtlOH'lII which, the motor connecting rods directly drive a crank connected with one of the live axles;- Fig; 2 shows a modified form in which the rods are connected to a point between two cranks.

In'the example illustrated in Fig. 1 m and denote the two motor cranks which through the intermediary ofthe jointed COIP. 'pling rods I0 I0 ,act on the central driving crank of; the three driving ,cranks t t 25 which are'interconnected by horizontal cous The coupling rod 10 is provided at'its lower end with the slotted guide f in which the driving crank 25 may move vertically up and down corresponding tothe play'of the spring of the corresponding "driving or live axle,- whereas the coupling rod 70 is connected to k by means of the link g so as to'avoid jamming in-the slot 7'. The .rods 8 are provided with jointsl Z or equivalent means which allow ofian independent play ofthe live or drii ing axles.

The simultaneous position of the driving rods on the other side of the vehicle is shown in dotted lines, the cranks being set substantially 90 apart. I

The form of the invention shown in Fig. 2 is similar to that illustrated in Fig. 1 with the exception that in this latter figure the coupling rods I0 70 do not act on a driving crank, but on any suitable pol-3t of the horizontal coupling rods 8 connecting the driving cranks t wh ch point is situatedbetwecn two driving cranks. The slot may in this case ,be dispensed with as at this point 'no elasticity in a vertical direction need be absorbed.

It will be understoodthat the specific forms described and illustrated are given as examples only.

- Where the word flexible is used in the specification orclaims it. is to be understood in twowa'ys, first, the two inclined rods k 70 may be connected together-with the interposition of'ajoint (g) 5 and second, itis possible make one or other ofthe rods elastic so that the joint maybe omitted. One of the two arrangements is required in order to avoid jamming in consequence of the *wear of the bearings and inaccuracy in erecting. .-Hav'ing now described my invention what I claim asnew'an'd desire to secure by Letters Patent is 1. A vehicle drlve including two motors and three pairsof driving wheels, said motors being arranged above said wheels,' a

"crank in connection with each of said motors and each of said wheels onone side of the Vehicle and a iturther crank in connection with each of said motors and each of said Wheels on the other side of the vehicle; said cranks being displaced b v'90 in relation to one another, coupling rods connecting the wheel cranks respectively on each side of the vehicle and independently arranged coupling rods connecting the motor cranks on each side of the vehicle with said wheel crank coupling rods on each side of the vehicle; as set forth.

2. A vehicle drive including two motors and four sets of driving wheels, said motors being arranged above said wheels, a crank in connection with each of said motors and each of said wheels'on one side of the vehicle .and a further crank in connection with each of said motors and each of said wheels on the other side of the vehicle. said cranks being displaced by 90 in relation to one another. coupling rods connecting the wheel cranks respectively on each side of the vehicle and independently arranged coupling rods connecting the motor cranks on each side of the vehicle with a point between two wheel cranks in aforesaid wheel crank coupling rods; as set forth. 3. A vehicle drive comprising two motors,

[a pluranty of driving wheels; on each side oftli vehicle, said motors bein above said wheels, coublfng L g for the driving wheels of each side, and "means'for situated independently transmitting the "motion "of both motors to the drivingiz -wheels on eachi side of the vehicle.

4. A vehicle drive comiirising two inoto'rs and a plurality of dr ving axles-said motors being situated above said axles, means'transmitting the motion of one axle to the other axles and means arranged independently of each other-transmitting the motion of the two-motors to one. of said axles through mu ua-lly flexible coupling rods; as set forth. (-A vehicle drive comprising a-plurality of driving shafts and a plurality of driven shafts, means connecting thedriven shafts of one side of the vehicle said means includa flexible-connection and means connecting the driven shafts of the other side of said vehicle, said means also including a flexible connection and displaced through an angle with relation to said means further means connecting" one of the driving shafts with a point in the means connecting the driven shafts on each side-of the vehicle respectively and independent means also on each side of the vehicle flexible with respect JACOB BUCHLI.
